WINDOW.

Application filed May 17, 1915.

To all whom it may concern Be it known that I, JOHN PETERSON, citizen of the Kingdom of Sweden, resident of Minneapolis, county of Hennepin, State of Minnesota, have invented certain new and useful Improvements in Windows, of which the following is a specification.

The object of my invention is to provide a window frame of such construction that the sash can be withdrawn and inverted for washing or other purposes without disconnecting the sash weight cords.

A further object is to provide a window frame construction which will permit convenient loosening of the sash in case of binding or sticking without disturbing the window stops.

A further object is to provide means for permitting the removal of the sash which can be applied to a window that is already in use in a. building.

Other objects of the invention will appear from the following detailed description.

The invention consists generally in various constructions and combinations, all as hereinafter described and particularly pointed out in the claims.

In the accompanying drawing forming part of this specification Figure 1 is a vertical sectional View through a window frame embodying my invention, taken on line mw of Fig. 2, Fig. 2 is a horizontal sectional View on the line g of Fig. 1, Figs. 3 and 4 are detail perspective views, illustrating the manner of constructing the meeting rails of the sash to allow for the edgewise movement thereof in separating the sash from the frame, Fig. 5 is a detail sectional View showing the preferred manner of mounting the movable strips in the window jambs, Fig. 6 is a detail sectional view, showing the manner of securing the sash weight cord to the sash.

In the drawing, 2 represents the window sill, 3 the jambs, 4 and 5 the inside and outside stops. 6 represents the stops between the stiles 7 and 8. These stiles have sockets 9 therein and holes 10 of greater diameter than said sockets and communicating therewith, plates 11 being secured in the bottom of said holes and having openings 12 to receive the sash cord 13. This cord is knotted in the socket 9 and held therein by a plate 11. Sa h eights. 1% are connected with the Specification of Letters Patent.

cord for eachstileof the'sash. It is often desirable, particularly in oflicebuildings or hotels and the like, where windows have to be washed at a considerable distance from the ground and where the window washer I usually stands on the sill on the outside of the window in washing the outer surface-of the glass, a single mist-step being almost sure to result fatally, todispense with the necessity of the window washer standing on the outside of the window and endangering his life, or limb, or fastening himself to the building by straps or a harness of some kind. I therefore provide a device which will permit reversal of each sash easily and conveniently and'allow thewindow washer access to the outer surface'of the glass while standing in the room in which the window is located. I provide longitudinal openings 15 in the window frame jamb extending a sufficient distance therein to receive one of the sash stiles and allow the sash to be moved edgewise a suflicient distance to disengage the other stile from its jamb. In each end of the opening I prefer to provide a recess 16 to receive tongues 17 formed-on the end of a plate 18, the inner face of said plate fitting into the opening in the jamb and flush with the surface of the jamb. This plate I prefer to hold yieldlngly by means of an extension spring 19 attached at one end to a bar 20 carried by a plate 21 on the tongues 17, the other end of said spring being mounted on a block 22 into which a screw 23 is tapped and fits into a socket in a plate 24 in the jamb. When pressure is applied to the inner face of the plate 18, it will be pressed outwardly against the tension of the springs 19, there being one of these springs at the top and bottom of each jamb plate. This temporarily increases the distance between the opposite jambs and allows the sash to be slipped into the opening in the j amb on one side a sufficient distance to release the opposite stile of the sash from the window stops and permit the sash to be turned over or reversed and present the outer surface of the window in position to be washed by a personstanding on the inside. This provision for lateral or edgewise movement of the sash is also advantageous in case the window binds or sticks because of fresh paint or through swelling of the sash, as it allows the movement of the sash without disturbing the window stops.

The meeting rails of the sash are provided with beveled surfaces which fit snugly against one another when the window is closed to exclude cold air and dust. The diagonally opposite ends of these meeting rails have recesses 26 formed by cutting out wedge-shaped blocks 27, these blocks being glued or otherwise secured to the opposite ends of the beveled faced rails, so that the block of one rail will enter the recess of the other rail. These blocks are cut out to provide for an edgewise movement of the sash, the shoulders allowing sufficient lateral movement of the sash to clear the window jambs.

The stiles of the sash are provided with vertical grooves 28 to receive the sash weight cords.

This invention may be applied to any size of window, either new or old, and will permit the convenient reversal of either sash whenever desired.

I claim as my invention:

1. A window frame having jambs provided with longitudinal openings therein and plates fitting within said openings, the ends of said plates being recessed to form tongues to enter corresponding recesses provided in said jambs, said jamlos having sockets therein and coiled springs fitting within said sockets and connected at one end to said jambs and at their other ends to said plates, the inner surfaces of said plates being normally flush with said jambs, stops for said sash, said openings being of sufiicient length to allow said sash to be moved edgewise therein, for the purpose specified.

2. A window frame having longitudinal openings in its jambs and plates yieldingly mounted in said openings, window sash fitting within said frame, the meeting rails of the upper and lower sash having beveled surfaces provided with recesses at one end of each rail and blocks mounted on the corresponding end of the other meeting rail to enter said recesses, stops for said sash, said recesses allowing said sash to be moved edgewise into said openings against the pressure of said plates, for the purpose specified.

3. A window frame having jambs pro vided with longitudinal openings therein and plates fitting within said openings and recessed at the ends to form tongues to enter corresponding recesses in said jambs, said jambs and tongues having sockets therein, coiled springs fitting within said sockets, plates mounted on said tongues and to which one end of the springs is secured, blocks fitting within the other ends of said springs and attached thereto, and screws mounted in plates seated in said jambs and tapped into said blocks, the inner surfaces of said plates being normally flush with said jambs, stops for said sash, said openings being of sufficient length to allow said sash to force said plate outwardly a sufficient distance to disengage the opposite edge of the sash from its stop.

In witness whereof, I have hereunto set my hand this 15th. day of May, 1915.
